Anatomy and Physiology - task 3: Report
The muscular system is responsible for the movement of the human body. There are about 700 named muscles that are all attached to the skeletal system and they make up roughly half of a person’s body weight. There are three different types of muscle tissue: Cardiac, Skeletal and Smooth.
1. Cardiac Muscle. Cardiac muscle is only found in the heart, and is responsible for pumping blood around the body. You cannot control cardiac muscle consciously and therefore it is involuntary muscle; unlike other types of muscle cardiac muscles never get tired. It works automatically and constantly without ever pausing to rest. Cardiac muscle contracts to squeeze blood out of your heart, and relaxes to fill your heart with blood
2. Skeletal Muscle. Skeletal Muscle is the only voluntary muscle in the human body, it is controlled consciously. Every physical action that a person consciously performs (e.g. speaking, walking, or writing) requires skeletal muscle. The function of skeletal muscle is to contract to move parts of the body closer to the bone that the muscle is attached to. Most skeletal muscles are attached to two bones across a joint, so the muscle serves to move parts of those bones closer to each other.
3. Smooth Muscle. Smooth muscle is found inside of organs like the stomach, intestines, and blood vessels. The weakest of all muscle tissues, smooth muscle makes organs contract to move substances through the organ. Because smooth muscle
Natalia Chapman Anatomy and Physiology Exam Re-grade III 1a. A – For this question I lost points because I honestly got mixed up with the words spermatogonia and spermatozoon. Spermatogonia is actually the specialized cells that sperm production beings with, these cells lie on the basement membrane of the seminiferous tubule. When the spermatogonia begin to divide sperm production begins. B – The correct answer should be spermatozoa or spermatozoon. In the first division of sperm development…
Chap. 7 1. Compact bone: also called cortical bone. Dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces. Spongy bone is less dense, lighter than compact bone. Looks like a sponge. No osteons. 2. Intervertebral discs, pubic symphsis, cartilage pads of the knee 3. Calcium and phosphates. Calcium is used for muscle contraction, blood clotting, and nerve impulses and keeps bones strong. Phosphates is required for ATP utilization…
The food’s nutrients are now being absorbed in to the blood, and the veins from ileum are now draining into superior mesenteric vein. Superior mesenteric vein and the splenic vein then combine and form hepatic portal vein where it leads to the liver. The portal venous system located in the liver is delivering blood to the capillary system. From there, blood is now flowing up into the inferior vena cava and to the right atrium, from there down to the right ventricle and then down to the pulmonary…
M2 Anatomy and physiology Craig Halliwell Measurements of the body's most basic functions. Height Height is usually measured while the person is standing up with their shoes off. It is used to determine if children are growing at a normal rate for their age and to determine if older people are shrinking which could be a sign that they may be developing bone loss, which is often linked to osteoporosis Weight Weight is…
1. The study of anatomy, physiology, and histology is important to cosmetologists because you need to know certain parts of the body to be able to understand how they work. 2. Anatomy is the study of the human body structures that can be seen with the naked eye and how the body parts are organized; it is the science of the structure of organisms or of their parts. Physiology is the study of the functions or activities performed by the body's structures. Histology, also…
Not An Old Person's Disease Part I—"Soaking Up the Sun" by Jennifer Miskowski and Anne Galbraith* Department of Biology University of Wisconsin—La Crosse Judy sat up, took a swig from her water bottle, and wiped the sweat off of her face. She glanced at her watch and frowned. Had they only been out here for half an hour? Man, trying to get a good tan was way too much work. She glanced over at Mariah who was sleeping peacefully in her lounge chair. No wonder she looked like a Greek goddess every…

Greek and means "to cut apart". D. German and means "body". E. Italian and means "form". 2. Anatomy is the study of: A. stars. B. function. C. sharp tools. D. structure and form. E. word histories. 3. Since the body has been the same for thousands of years, anatomy is considered a static classification system instead…
Study Guide 1.Define Anatomy & Physiology Anatomy: Is the science of body structures and the relationships among structures. Physiology: is the science of body functions, that is how they work. 2. Levels of Structural Organization Chemical: Composed of all Atoms and Molecules essential for maintaining life. Cellular: Consists of cells, the basic structural and functional units of an organism and the smallest living units in the human body. Tissue: Formed by tissues, groups of cells and the materials…
