Digestive System Study Guide 1. Define the term digestion and explain its significance. The chemical and mechanical process of breaking down food and its absorption. Its essential to maintaining life. 2. Distinguish between mechanical digestion and chemical digestion. Chemical digestion is where complex food molecules are broken down to the basic building blocks by enzymes. Mechanical digestion is chewing‚ churning and segmentation. 3. Discuss the five digestive processes that overview the many functions

Respiratory System A frog’s respiratory system is much different than humans. First‚ the lungs in a frog have thin walls and are shaped like balloons. When frogs swim‚ they fill their lungs with air‚ which helps them stay buoyant while swimming. Frogs also do not have diaphragms compared to humans. They only breathe through their nose. They use muscles in their throat sacs to help move the air in‚ and then is pushed to the lungs. During this time‚ their mouth is closed. Body contractions allow

The cardiovascular system which impacts deeply on human consciousness. The heart and the body’s blood-transporting network of arteries‚ veins‚ and smaller vessels form the circulatory or cardiovascular system. As blood is continuously pumped out from the heart and around the system in two circuits‚ it carries oxygen and vital nutrients to all parts of the body and removes harmful waste products from tissues.

REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to

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

Structure of the heart: The heart is at the centre of the cardiovascular system. It is a hollow muscular pump that drives blood through the arteries‚ which allows it to reach the working muscles and tissues. The heart is split into two halves. The right side of the heart is separated from the left by a solid wall known as the septum. This prevents any blood on the right side coming into contact with the blood on the left side. The right side of the heart sends deoxygenated blood to the lungs in
