Circulatory system
What is the function of the circulatory system?
To circulate nutrients, gases (O2 and CD) hormones and other necessary material through the blood which then gets delivered to cells.
What is the function of the digestive system?
Breaks down and absorbs nutrient like glucose.
What is the function of the respiratory system?
To exchange gases (O2 and CD) between the atmosphere and the blood.
What is the function of the Endocrine System?
Makes and secretes hormones.
What is the function of the Nervous system?
The function of the Nervous System is to see and respond to stimuli inside and outside the body.
What is the homeostasis?
Internal stability.
What do absorption do?
nutrients get absorbed into bloodstream + get transported by circulatory system.
What is Breathing?
Breathing is the physical process where you inhale and exhale air in and out of your lungs.
What are target cells?
Cells that has receptors for a hormone.
What does the peripheral Nervous System do?
send nerve signals throughout my body.
What is blood?
Blood is both a fluid and tissue that contains red blood, white blood cells platelets and plasma
What is the stomach?
The stomach is the organ where further digestion through secretions of gastric juice, acids and enzymes. The chyme (digested food) is squeezed into the small intestine.
What is Respiration?
Respiration is the chemical reaction where O2 is used to breakdown glucose in order to create ATP
What are hormones?
A chemical substance produced in the body that controls and regulates the activity of certain cells/organs. *each hormone is specifically shaped,shape determines function.
What is the stimuli?
A thing or event that evokes a specific functional reaction in an organ or tissue.
What is plasma?
Plasma is the liquid part of blood that is made of water, salt protein.
What are pancreas/liver
Accessory organs that secrete digestive juices and enzymes to further digest chyme.
what are Lungs?
Lungs are large spongy organs containing many capillaries largest organ in the respiratory system.
what is a pituitary gland
master gland- controls other glands
What is the function of the neuron?
Neurons transmit nerve impulses from place to place in the body. Nerve Impulses are electrical discharges that are transmitted along the cell membranes of neurons
What is the capillary?
The blood transports all the necessary materials (including glucose and oxygen) to cells. These materials then diffuse from the blood, through the cell membrane and into the cell.
What is the nutrient Absorption?
Nutrients (glucose, O2,CO2) are inside of the small intestine then diffused into the bloodstream
what is the function of gas exchange in the lungs
Gas exchange happens in the alveoli through the process of diffusion. oxygen diffuses in the blood and is carried throughout the body through the circulatory system.
What are Thyroid?
Produces hormones that regulate the rate of metabolism in the body.
How are nerve impulses transmitted?
An electrical signal is initiated near the cell body portion of the axon This signal is then transmitted along the axon (and not back to its dendrites) until it reaches its axon terminals At the axon terminals the neuron sends its neurotransmitter to other target neurons.
