Physiology Assignment Name Class Date Every organism has specific characteristics that make it ideal for living in the certain environment that it resides. For example‚ owls are birds that have adapted to hunting at night. They have many adaptations that allow them to be successful night hunters. One adaptation that the owl has involves their eyesight. The eyes of owls are sunk in. This allows an owl to collect and intensify light making it better able

all members in a group‚ not only because people have different physical traits‚ but also different diet and living habits. There are three major body types: Ectomorph‚ endomorph and mesomorph. People who are described as Ectomorphs usually have lean muscle mass; they have small frames and do not gain weight easily‚ and therefore‚ have a slim appearance. Ectomorphs have long limbs‚ narrow hips and small shoulder width; their muscule strength is usually unable to afford heavy training‚ and therefore‚

Chapter 5: The Skeletal System I. Introduction. The skeletal system consists of the bones‚ along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints. A. Functions of the Skeleton. 1. The skeleton supports the body. 2. The skeleton protect soft body parts. The skull protects the brain‚ the rib cage protects the heart and lungs‚ and the vertebrae protect the spinal cord. 3. The skeleton produces blood cells. Red bone marrow contains

Muscle contractions tend to be smooth and vary in strengths‚ depending on the demands placed on them. The variations of strength are called graded muscle responses. There are two ways a muscle contraction can be graded‚ either by changing the frequency of stimulation or by changing the strength of the stimulation. When a muscle is responding to a change in stimulus frequency‚ the nervous system will reach a greater muscular force when increasing the firing of motor neurons. This causes a wave or

Module 04 Case Study: Bone Tissue Part I— “Marissa” Questions 1. Describe bone tissue and the role each component plays in bone physiology and remodeling. What is the difference between compact and spongy bone? (2 points) Bone tissue is composed of bone cells and extracellular matrix. It is continuously remodeling its extracellular matrix according to the stresses placed upon it. It has a lot of blood flow and it is supplied by the nervous system. The bone cells includes; Osteocytes‚ osteoblasts

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart‚ which is a muscular pumping device‚ and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body.
