Circulatory system (detailed) |
The circulatory system also called the cardiovascular system consists of the heart blood vessels (arteries veins and arterioles) in blood. It supports the circulation and distribution of various substances throughout the body. Oxygen, hormones, and nutritions from foods are some of these substances. |
Transportation highway. Heart, veins, arteries, and capillaries. |
|
Digestive system (detailed) |
The digestive system consists of all the organs from the mouth to the anus involving the indigestion and breakdown or processing of food. The organs along this path include the esophagus, stomach, small intestine, and large intestines, rectum and anus. The digestive system manufacturers enzymes that break down food so that the nutrients can be easily passed into the blood for the use throughout the body. Any food that is not digested is expelled through the anus. The absortion of nutrients actually occurs in the small intestine, which consists of the duodenum, jejunum, and ileum. After that, the colon removes water from the waste that remains. To other organs included in the digestive system are the liver and pancreas. The liver produces bile that helps break down fat, and the pancreas delivers enzymes to the small intestine that aid in digestion. |
Where food is broken down |
|
Endocrine system (detailed) |
The endocrine system serves to controls body functions. Glands in the endocrine system secrete hormones that travel through the blood to organs throughout the body. Glands such as the pineal, pituitary, thalamus, hypothalamus, thyroid, thymus, and adrenal regulate processes such as growth and metabolism. The pancreas, testis, and ovaries also have endocrine functions, even though they are part of the other body system. |
Controls hormones |
|
Integumentary system (detailed) |
The integumentary system consists of the skin, mucus membranes, hair, and nails. It protects internal tissues from injury, waterproofs the body, and helps regulate body temperature. This system also serves as a barrier to pathogens (microorganisms capable of producing diseases). |
|
|
Lymphatic system (detailed) |
The lymphatic system consists of lymph nodes, lymph vessels that carry lymph (a clear fluid rich and antibodies), the spleen, the thymus, and the tonsils, which are made up of lymphoid tissue. It supports the immune system by housing and transporting white blood cells to and from lymph nodes. The lymphatic system also returns fluid that has leaked from the cardiovascular system back into the blood vessels. |
|
|
Muscular system (detailed) |
The muscular system consists of skeletal muscles, tendons that connect muscles to bones, and ligaments that attach bones together to form joints. The cardiac and smooth muscles are not included in the organ system. |
|
|
Nervous system (detailed) |
The nervous system consists of the brain, spinal cord, and nerves, and it serves as the body's control system. Sensory receptors detect stimuli that can occur both inside and outside the body. The conduction of nerve impulses along nerves is extremely fast, making it possible for immediate reflexive responses to protect the body from threats. Once a threat is detected, the nervous system activates and appropriate muscles or glands to respond. |
|
|
Reproductive system (detailed) |
The main purpose of the reproductive system is to produce offspring. This system consist of the testes, penis, ovaries, vagina, and breasts. The reproductive system is specialized in men to produce sperm and in women to produce eggs (or ova). The reproductive organs also house hormones that encourage or suppress activities within the body (example libido and aggression) and influence the development of masculine or feminine body characteristics. |
|
|
Respiratory system (detailed) |
The respiratory system keeps the body's cells supplied with oxygen and removes carbon dioxide as it is released from the cells. It consists of the nasal cavity, pharynx, larynx, trachea, Bronchi, and lungs. The lungs house tiny air sacs called alveoli. It is throught the walls of the alveoli that oxygen and carbon dioxide move in and out of the lungs via small blood vessels called arterioles. |
|
|
Skeletal system (detailed) |
The skeleton system provide support and protection for the body and its organs and supplies a framework that, when used in conjunction with the muscles, it creates movement. It consists of bones, cartilage, ligaments, and joints. The skeletal system also serves as storage for minerals such as calcium and phosphorus. |
|
|
Urinary system (detailed) |
The urinary or excretory system helps maintain the water and electrolyte (sodium, chloride, and potassium are electrolytes) balance within the body, regulates the acid-base balance of the blood, and removes all nitrogen contained waste from the body. The nitrogen-containing wastes are byproducts of the breakdown of the proteins and nucleic acids. |

|
Epithelial tissue

|
|
Epithelial Tissue
|
Epithelium serves two functions. It can provide covering (such as skin tissue) or produce secretions (such as glandular tissue). Epithelial tissue commonly exists in sheets and does not have its own blood supply. Subsequently, epithelium is dependent on diffusion from the nearby capillaries for food and oxygen.Epithelial tissue can regenerate easily if well nourished. Epithelial tissues are classified according to two criteria: number of cell layers and cell shape. Simple and stratified epithelial tissues vary in relation to the number of cell layers. Simple epithelium contains one layer of cells. It is found in body structures where absorption, secretion, and filtration occur. Stratified epithelium has more that one layer of cells and serves as protection. The shape of epithelial cells includes squamous, cuboidal, and columnar.
|
|
|
Connective Tissue
|
Connective tissue is found throughout the body; it serves to connect different structures of the body. Connective tissue commonly has its own blood supply; however, there are some types of connective tissue, such as ligaments, that do not. The various types of connective tissue include bone, cartilage, adipose (fat), and blood vessel.
|
|
|
Muscle Tissue
|
Muscle tissue is dedicated to producing movement. There are three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscle supports voluntary movement since it is connected to bones in the skeletal system. Voluntary movements are consciously controlled by the brain. Smooth muscle is under involuntary control. Which means it cannot be consciously controlled. It is found in the walls of hollow organs, such as intestines, blood vessels, bladder, and uterus. Like smooth muscle, cardiac muscle movement is involuntary. Cardiac muscle is found only in the heart.
|
|
|
Nervous tissue
|
Nervous tissue provides the structure for the brain, spinal cord, and nerves. Nerves are made up of specialized cells called neurons that send electrical impulses throughout the body. Support cells, such as myelin, help protect nervous tissue.

|
Circulatory system
|
|
How does the heart work?
|
Oxygenated blood enters into the heart through the superior and inferior vena cava. The blood travels into the right atrium and, during contraction of the atrium, flows through the tricuspid valve into the right ventricle. The blood is pushed through the pulmonary valve into the pulmonary artery and lungs when the right ventrical contracts. Here, it picks up oxygen. The oxygenated blood is then carried back to the heart (by the pulmonary veins), into the left atrium, through the mitral valve, and into the left ventricle. Contraction of the left ventricle forces the blood through the aortic valve, through the aorta, and out to the entire body.
|
Circulatory system
|
|
Heart consists of four chambers:
|
the right and left atriums and the right and left ventricles. It also has four valves that prevent the flow of blood back into the heart's chambers after a contraction. The valves include the tricuspid and pulmonary on the right side of the heart and the mitral and aortic on the left side of the heart.
