Cardiac muscle

All heartbeats consist of a mechanical component and an electrical component. The heartbeat is created by cardiac depolarization caused by electrical currents that induce muscle contraction. The electrical component of the heartbeat begins in the Sinoatrial (SA) Node and its function is to send electrical impulses that stimulate your heart to beat, and these impulses induce the atria to contract. As the atria contract, the impulse moves on to the Atrioventricular (AV) node which leads the…

the body’s condition at rest is very different than the energy requirement during maximal exercise. At rest, the muscle intake of gas is very little, but during activity, oxygen consumption is multiples due to the intense oxygen demands of the muscles. Other parameters that are expected to change during exercise are metabolic rate, heart rate and blood pressure, stroke volume, cardiac output, and total peripheral resistance. The energy required to maintain the bodily functions comes from the…

musculo skeletal system consists of bones of the skeleton, muscles, cartilage, tendons, ligaments and joints, they all work together to provide the body support, protection and movement. The bones protect the body’s internal organs for example the rib cage protects the lungs, the skull protects the brain and the spine protects the spinal cord, it also supports the weight of the body and moves the body with the help of muscles. The muscles hold these bones in place, they assist with movement by…

The heart is one of the major organs in the body that is essential. The heart is considered a pump that helps the blood flow, continuously, throughout the body. The heart is located under the rib cage, between the lungs, and more on the left side of the breastbone. It has two major coronary arteries, electrical impulses, four chambers, and four valves to help the blood flow one way. Deoxygenated blood enters the right atrium from the superior and inferior vena cava. When the right atrium…

Endothermy has a lot of benefits and costs compared to ectotherms. Endotherms depend on their bodies metabolism to produce enough heat to raise their body temperature. Endotherms balance heat production with heat loss. Each endotherm has a range of environmental temperatures that keeps its body stable and it does this by regulating the heat loss and heat production. They regulate their body heat by vaping their metabolic rate and change its rate of heat loss by adjusting their insulation.…

classifications of issues: cardiogenic (issues related with the heart), hypovolemic (aggregate volume of blood accessible to circle is low), and septic stun (disease in the blood). Cardiogenic stun can be brought on by any malady which keeps the heart muscle from pumping emphatically enough to course the blood regularly. Heart assault, unsettling influences of the electrical musicality of…

the heart is a complex organ made of muscle and is compromised of four chambers including a right and left atrium and corresponding ventricles. the function of the heart is to pump oxygen rich blood throughout the body while receiving blood and sending it to the lungs to be re oxygenated then repeating the cycle. all of the body's different tissues require this oxygen rich blood to perform their functions. however, there are many problems that can affect the function of the heart. some of these…

Muscles in a way are the most important parts of the body. If we didn’t have muscles it would be impossible to move around, and do things. Muscles make everything we do possible, but there is more to muscles than meets the eye. Yes there are the kinds of muscles which allow us to walk and pick up things, but there are also different kinds of muscles which if anything are equally important. Before we dive into the kinds of muscles and their functions, let’s get a better idea of how muscles work.…

Reason ⅰ : To remove lactic acid in blood and skeletal muscle cells When the degrees of exercise increase, → The skeletal muscles contract more frequently. → Not enough oxygen is supplied to the skeletal muscles for aerobic respiration. → Skeletal muscle cells carry out anaerobic respiration to generate additional amount…
