Human heart

The human body is composed of eleven major systems that all work together to hold a stable internal environment: homeostasis. Each system consists of different organs that all play important roles in maintaining homeostasis. The circulatory, respiratory and renal systems greatly affect each other in the keeping of the internal environment. Homeostasis is defined as the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to…

The walls of the heart have three layers of tissue: endocardium which is a single layer of epithelial cells, myocardium this is cardiac tissue, and epicardium which is serious membrane and epithelial tissue. They are surrounded by a pericardium layer that is connective tissue…

gas exchange. To extract energy from the sugars and acids in our body, oxygen is needed. During the process of extracting energy carbon dioxide is produced and the body must rid its self of this toxin. Movement of the cellular molecules in the human body in a manner that is not directional is called diffusion. Net diffusion occurs when there is a directed movement and differences in concentration of the molecules. As the body inhales, oxygen from our environment is taken into the body. As…

Muscle tissue is one of the four tissues types that exist in the human body. There are three different muscle tissues, skeletal, cardiac, and smooth. Skeletal muscle tissue cells are long, striated, and have many nuclei. Cardiac muscle tissue, just like the skeletal is also in striations. These cells are short and branched. Unlike, the skeletal muscle tissue these cells die single nucleated. They are connected by intercalated discs. Smooth muscle tissue is not striated. Its Cells are short and…

Introduction I chose to write about the most versatile animal that I can think of, the coyote! The coyote is a native to my original home, Wisconsin and to my current home, Colorado!

Every minute, the heart pumps about 1.5 gallons of blood through the body. The heart is “just above the diaphragm, between the right and left lungs” (Balaban 197). About two-thirds of the heart are located on the left side of the chest, while only about one-third of the heart is located on the right side of the ribcage. The cardiovascular system provides a transport system between the heart and lungs. The heart’s most important function is to indulge indispensable nutrients to the tissues and to…
