1 Hypothalamus – a small region of the brain that is a major link between the nervous and endocrine system. The hypothalamus controls the autonomic nervous system and regulates body temperature, hunger, thirst, fear, rage, and sexual behavior. The hypothalamus control feeling such as pain, stress, and emotional experiences. (1)
2 Pituitary gland – the “master endocrine gland” because it secretes many hormones that control other endocrine glands. It is a “pea-shaped structure that attaches to the hypothalamus by a stalk. The pituitary gland contains an anterior lobe called the anterior pituitary that function to secrete hormones that regulate bodily activities from growth to reproduction.

2. Cardiovascular System: Observe the diagram showing the major structures of the cardiovascular (circulatory) system. Using the textbook and Virtual Library resources, fill in the following table:
Cardiovascular System

Number Name of the Structure Major Function
1 Heart – shape like a cone lying on its side; its apex is the pointed, inferior part; the base is the broad, superior part. The function of the heart is to pump blood through blood vessels to all part of the body tissues. (1)
2 Pericardium – the membrane that surrounds and protects the heart. It consists of outer fibrous layer and inner pericardium.
3 Right atrium – receives blood from three veins such as the superior vena cava, inferior vena cava, and coronary sinus.
4 Right ventricles – form most of the anterior surface of the heart.
5. Left atrium – form most of the base of the heart and it receives blood from the lungs through four pulmonary veins. Blood passes from the left atrium into left ventricles through bicuspid valve.
6. Left ventricle – forms the apex of the heart. Blood passes from the left ventricles through the aortic valve into the ascending

    The heart has 4 sections inside: left and right atria and left and right ventricle. The right atrium receives blood that is low on oxygen molecules from the superior and inferior vena cavae. The superior vena cava is one of the largest veins in the body that brings de-oxygenated blood from the lower part of the body to the right atrium. The inferior vena cava is the other largest vein in the body that brings blood into the right atrium from the top of the upper parts of your body. The right atrium pumps blood through the tricuspid valve and into the right ventricle.…

    The four chambers are the left atrium, the right atrium, left ventricle and the right ventricle. The left atrium is the collecting chamber. It collects oxygen and rich blood returning from the heart. The right atrium is also the collecting chamber for blood returning from the trip. The left ventricle is a part of the pumping chamber and it pumps blood through all body parts.…

    Blood circulates through the heart in two ways. They are identified as the pulmonary circuit and the systemic circuit. The pulmonary circuit is simply the movement of blood from the heart, to the lungs, and back up to the heart again. Deoxygenated blood leaves the right ventricle of the heart and runs through the pulmonary artery; from here, the blood is pumped through the right atrium and into the right ventricle. The blood continues its course and travels through the lungs.…

    In the lungs the blood gets oxygenated and returns to the left atrium through the pulmonary veins. It passes through the left AV into the left ventricle and when the left ventricle contracts blood is forced through the aortic SL, into the aorta and distributed to the body (“The Heart and Heart…

    The heart has connective tissue in the form of fibrillary collagen that offers support (Burlew & Weber, 2000). The heart has cardiac muscle, which has intercalated discs to give the signal to contract and start the heartbeat (Ireland, 2012). Smooth muscle is also present in the arteries and vasculature (Xin, Olson, & Bassel-Duby, 2013). The heart also has parasympathetic and sympathetic nervous tissue in the form of fibers (Olshansky, Sabbah, Hauptman, & Colucci, 2008). All these tissue types serve their own functions, yet work together for the overall health of the organ.…

    The pulmonary artery extends into both of the lungs where the deoxygenated blood is replenished with oxygen and is send back to the heart through the pulmonary veins into the left atrium chamber 4 at this time the left and right atrium relax to intake oxygenated and deoxygenated blood respectively. Which is marked as a diastole (term used to describe the relaxation) [9]. Now the oxygenated blood is then send into the next chamber the left ventricle through the mitral valve by the contraction of the left atrium. Next the left ventricle contracts forcing the blood to be pumped out of the heart into the aorta8 through the aortic valve which shuts off close as the blood is pushed out to the aorta. The oxygenated blood then travels to the upper and lower parts of the body through large muscular arteries , then into smaller and smaller arteries , then arterioles and finally to the capillaries.…

    Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. • The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446). • From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446).…

    The movement of the muscle is automatic and constant rhythmic movements that won’t stop. It contractions of the heart consist of the heart taking blood out of the heart and then relaxes to fill the heart back up with blood (Martini & Nath,2014 p.689-692). Each cardiac muscle fiber is made up of a single nucleus that has the appearance of striated or striped. The appearance is light and dark bands. Dark bands are made up of thick protein filaments that are produced by myosin proteins.…
