Life in The Balance
The average body temperature for humans
What is 37 degrees celsius?
The fluid which is in the space between the cells, which collects the oxygen, nutrients, carbon dioxide, and metabolic waste that is left behind during the exchange between the cell and the capillaries
What is extra cellular fluid?
The part of the heart which has a thin layer of muscle tissue as they receive blood and do not pump it very far
What is the left and right atria?
The node that is located in the right atrium and spreads electrical impulses across the atria which causes them to contract
What is the Sino-Atrial Node(S-A node)?
The system where blood flows through tubes and is under pressure, which causes the blood to flow faster
What is a closed circulatory system?
The closing of blood vessels which happens in skin to avoid heat loss when the body is cold
What is vasoconstriction?
What is the thoracic duct?
The valves in the heart which are half-moon shaped and prevent backward flow of blood
What is semilunar valves?
The tissues that causes uniform contraction of muscles within the heart
What is nodes?
The pathway which supplies blood and nutrients to everywhere in the body other than the lungs, as well as takes away carbon dioxide and metabolic waste
What is systemic circulation?
The opening of blood vessels which takes place in the skin to promote heat loss when the body is hot
What is vasodialation?
The lymph duct that drains lymph from the right side of the chest and head, and right arm, and empties into the right jugular vein
What is the right lymph duct?
The thick and muscular wall that divides the two ventricles
What is the septum?
The part of the brain which controls the heart beat which can release noradrenaline and acetylcholine
What is the medulla oblongata?
The system where blood directly flows over body tissues in body spaces, does not need tubes to flow through, and is under very low pressure
What is open circulatory system?
The part of the organism which detects a change affecting the organism, and sends impulses to the brain
What is the sensory receptor?
The part of the lymph where the extracellular fluid drains into
What is the lymph capillaries?
The two chambers of the heart which have a thick layer of muscle tissue as they pump blood further than than the other chambers of the heart, and is composed of cardiac muscle tissue
What is the left and right ventricle?
The factors that can change the rhythm of the heartbeat
What is the temperature and chemicals in blood?
The pathway which involves the heart and lungs, and adds oxygen to the blood while removing carbon dioxide using the lungs
What is pulmonary circulation?
The part of the organism which determines the response needed for the detected change, which also determines which part of the body will respond, and to what to degree they will go to fix the change
What is the integrator, or the brain?
The part of the lymph which filters lymph fluid which removes cancer cells, bacteria, and viruses, as well as produces some types of white blood cells to aid the destruction of the filtered material
What is lymph nodes?
The large blood vessel that collects blood from the head, arms, and shoulders and empties into the right atrium
What is the superior vena cava?
The technology which can replace faulty S-A nodes and A-V nodes
What is artificial pacemakers?
The pathway that only involves the heart, by providing oxygen and nutrients, and removing carbon dioxide and metabolic waste from the cells of the heart
What is coronary circulation?
