What is are the functions of the nervous system?
Control reactions
What is the function of the endocrine system?
produces Hormones to maintain homeostasis.
What are four things that make up blood?
Red blood cells, white blood cells, platelets, and plasma.
What are three types of vessels?
Arteries, Veins, and Capillaries (thin layer of cells where gas is exchanged.)
What are the structures of the nervous system?
Nucleus, Dentrites, Axon, Myelin, Sheath, and node of ranvier.
What are hormones and where are they produced?
Glands.
What are the functions of red blood cells, white blood cells, platelets, and plasma?
Red blood cells: carry oxygen, white blood cells: protect from infection, Platelets: prevent and stop bleeding, Plasma: transport water, nutrients, hormones, and help remove waste.
What are three functions of the heart?
Veins: make blood travel to the heart, Arteries: make blood travel away from the heart, and capillaries: thin layer of cells where the gases are exchanged.
What are nurotransmitters?
Chemical messengers that help neurons communicate in with the cells and other organs.
How are hormones transported?
Hormones are transported through the circulatory system.
What is the structures of the respiratory system?
Nose cavity, Phazynx, Epiglottis, and Larynx.
what important molecules are transported at the lungs and alveoli?
What is the difference between sensory and motor neurons?
Sensory neurons send signals from the brain and spinal cord and motor neurons send the signals to the muscles and glands.
How do hormones communicate with cells?
Cells get the hormone signal when the hormone touches the receptor protein.
What is the function of the nose cavity, Phazynx, Epiglottis, and Larynx
Nose cavity: filters the air, Phazynx: pipes that let food and air in, Epiglottis: flap that protects the Phazynx, and Larynx: The voice box.
How does transport of these molecules happen when we breathe?
Suck in Air, breath of carbon dioxide.
What is the difference between nervous system communications and endocrine system communications?
Nervous system creates rapid communications while Endocrine system creates slower communications.
What are some examples of Negative feedback and Positive feedback?
positive feedback could be seen through blood clotting and negative feedback could be seen through sweating/ maintaining homeostasis.
What is the function of the heart?
pumps blood through the circulatory system.
Whats the structure of the circulatory system?
heart, vessels, and blood
