Physiology Stack 2
| What is the primary function of the circulatory system? | The primary function of the circulatory system is to transport nutrients, gases, hormones, and waste products throughout the body. |
| What is homeostasis and why is it important in physiology? | Homeostasis is the process by which living organisms regulate their internal environment to maintain a stable, constant condition, essential for survival. It involves feedback systems that balance factors such as temperature, pH, and electrolyte balance. |
| Describe the role of the autonomic nervous system in the body. | The autonomic nervous system (ANS) controls involuntary physiological functions, heart rate, digestion, respiratory rate, pupillary response. It is divided into the sympathetic and parasympathetic nervous systems, which generally have opposing actions. |
| Synapse | Synapse is the junction between two neurons, or between a neuron and a muscle or gland cell, through which nerve impulses pass. |
| Kidneys | The kidneys are vital excretory organs that filter the blood to remove waste products and excess substances, forming urine. They play a crucial role in maintaining homeostasis by regulating electrolyte balance, blood pressure, and fluid volume. |
| How do neurons communicate with each other? | Neurons communicate through electrical impulses "action potentials & chemical signals" via neurotrans. Action potential travels down neuron, leading to the release of neurotransmitters to the synapse, which then bind to receptors on the adjacent neuron. |
| What is homeostasis, and why is it important? | Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. It is crucial for the proper functioning of cells and organs, allowing the body to operate optimally and respond to stressors. |
| Hemoglobin | Hemoglobin is a complex protein found in red blood cells that binds to oxygen molecules in the lungs and transports them to tissues through the body. It also facilitates the return transport of carbon dioxide from cells back to the lungs for exhalation. |
| Endocrine System | a network of glands and organs that produce hormones that help regulate many bodily functions: |
| Autonomic Nervous System | is a network of nerves that help controls involuntary bodily functions, like breathing, heart rate, and digestion |
