| Question | Answer |
|---|---|
| What is action potential | is a rapid change in membrane potential that occurs in neurons, characterized by depolarization, repolarization, and hyperpolarization phases, allowing for the transmission of nerve signals. |
| How Does the All-or-None Law Work? | The all-or-none law states that the strength of a nerve cell or muscle fiber's response is not dependent upon the strength of the stimulus. A nerve or muscle fiber will fire if a stimulus is above a certain threshold. |
| Parasympathetic nervous system | The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body's rest-and-digest response. |
| Sympathetic nervous system | system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body's rest-and-digest response. The sympathetic nervous system (SNS) is one of two main divisions of the autonomic nerv |
| Endocrine System | Your endocrine system is in charge of creating and releasing hormones to maintain countless bodily functions. Endocrine tissues include your pituitary gland, thyroid, pancreas and others. |
| What is the function of the endocrine system? | The main function of your endocrine system is to release hormones into your blood while continuously monitoring the levels. Hormones deliver their messages by locking into the cells they target so they can relay the message |
| What are the great vessels of the heart | The great vessels of the heart are major blood vessels that connect directly to your heart. These arteries and veins circulate blood between your heart and lungs, and between your heart and the rest of your body. |
| Pulmonary circuit | Your pulmonary circuit sends blood between your heart and lungs. First, oxygen-poor blood travels from your heart to your lungs. There, it receives oxygen and gets rid of waste. This refreshed blood then travels back to your heart. |
| Systemic circuit | Your systemic circuit sends blood between your heart and the rest of your body. First, oxygen-rich blood leaves your heart. It circulates throughout your body, where it delivers oxygen, nutrients and hormones to your organs and tissues. It also picks up w |
| What is the lymphatic system | Your lymphatic system is a network of organs, vessels and tissues that work together to move a colorless, watery fluid (lymph) back into your circulatory system (your bloodstream). |
| What are the lymphatic system organs? | Bone Marrow, Thymus, Lymph Notes, spleen |
| The trachea | s a strong tube that contains rings of cartilage that prevent it from collapsing. |
| Factors Affecting Gas Exchange: | The efficiency of gas exchange can be influenced by several factors, including the surface area of the alveoli, the thickness of the respiratory membrane, and the concentration gradients of the gases involved |
| Mechanical Digestion | is a physical process in which food is broken into smaller pieces without becoming changed chemically. It begins with your first bite of food (see Figure 15.3.3) and continues as you chew food with your teeth into smaller pieces. |
| Enzymes | are proteins that catalyze, or speed up, biochemical reactions. Digestive enzymes are secreted by exocrine glands or by the mucosal layer of epithelium lining the gastrointestinal tract. |
