role of energy in the body The three systems in our body that work together are cardiovascular‚ respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system; also I am going to explain the physiology of the three named body systems in relation to energy metabolism. Respiratory System The respiratory system consists of tissues and organs in our body which are formed into groups. The system includes airways‚ lungs‚ blood vessels

Unit 1- Principles of Anatomy and Physiology Functions of the skeletal system There are five main functions of the skeletal system. To protect‚ to support‚ movement‚ cell production and storage. The skeletal system protects delicate and important organs from harm. An example of this is the ribcage. This protects your heart and lungs from anything that tries to harm it. Another example is the brain. The brain is protected by the skull. The skeletal system also provides support for the body as it

In general appearance‚ Gray Wolves resemble a large dog‚ but wolves have longer legs‚ larger feet‚ a narrower chest‚ and a straight tail. The gray wolf’s head is large and heavy‚ with a wide forehead‚ strong jaws‚ and a long muzzle. The ears are small and triangular. They carry their head at the same level as the back‚ raising it only when they’re alert. Their fur is thick‚ with an outer layer composed of coarse hair‚ and a soft undercoat. Their coat color is usually grey flecked with black but can

Review Sheet 1 Results 1. Describe two variables that affect the rate of diffusion. Your answer: Two variables that affect the rate of diffusion are the MWCO membrane and the solute concentration. Increasing the membrane size and solute concentration will also increase the average diffusion rate. Decreasing the membrane size and solute concentration will reduce diffusion rates and can even prevent all diffusion. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane

Skeletal Muscle Physiology Activity 1 1. Skeletal muscle fiber- long‚ cylindrical cell with multiple oval nuclei arranged just beneath the sarcolemma Motor unit- all of the muscle cells controlled by a single motor neuron Skeletal muscle twitch- a single stimulus-contraction-relaxation cycle in a skeletal muscle Electrical stimulus- uses an electrical current to cause a single muscle or a group of muscles to contract Latent period- the time between the stimulation of a muscle and the start

HB105: Introductory Physiology The Action of Enzymes Introduction An enzyme is located in all living cells‚ and is a complex protein molecules. These protein based molecule act as a catalyst. This is a compound that aids chemical reactions without its own structure and state being changed during the process. Catalysts speed up chemical reactions‚ changing substrates into specific produce. Without these enzymes life would not exist. Enzymes are fundamental to all living things as they speed up
