What else can I help you with?
What are three things muscles can do?
Allows for organism movement (skeletal muscles) or organ movement (cardiac muscles, smooth muscles of the gastrointestinal tract) Generates heat (in endotherms) Allows for blood to return to the heart after it has flowed to the extremities (by squeezing the veins when they contract)
What allows the movements of the blood in and out of the heart?
contraction and relaxation of the heart muscles
What is the regular wave like movement of the blood pumped by the heart through the blood vessel?
upper chambers of the heart
What movement of blood to the heart is tissues?
coranary circulation
Why are veins important in blood circulation?
Veins are responsible for the movement of deoxgenated blood from the heart
How does movement of electrical impulse relate to the contraction of the chambers of the heart?
The movement of electrical impulses in the heart coordinates the contraction of its chambers. The impulses initiate the contraction by stimulating the muscle cells, causing them to contract in a coordinated way. This results in the rhythmic pumping action that drives blood flow through the heart and to the rest of the body.
The heart is an involuntary which protect what?
The heart is protected by the cardiac muscle which is an involuntary muscle that allows the heart to pump blood.
What makes the throbbing of the pulse?
When your heart beats it moves blood and the movement of blood is ur pulse
What part that takescare of movement of blood withinthe heart and the lungs?
lymph
What part of the heart that allows the blood to flow in one direction?
the valves
What assists in the movement of blood throgh the veins other than the beat of the heart?
As skeletal muscles contract, blood is forced along the veins to the heart.
Why human heart is cone shaped?
The human heart is cone-shaped to optimize its function as a pump. This tapered shape allows for efficient blood flow dynamics, facilitating the movement of blood from the heart into the arteries. The apex of the cone points downward and to the left, which aligns with the orientation of the major blood vessels and enhances the heart's ability to contract effectively. Additionally, the cone shape helps accommodate the heart's chambers and valves, ensuring proper circulation throughout the body.
