The heart forces the ‘oxygenated’ blood through a range of connecting blood vessels specifically speaking arteries which travel around your body providing your cells with the necessary materials that the blood contains. As the blood reaches your cells the oxygen is released in order for the cells to function. The cells then give out waste materials which can include co2 and water. In order for your blood to receive these waste products they absorb it. We now have deoxygenated blood which goes through your veins aiming towards your heart.
The mesosalpinx is a fold in the expansive ligament. The distal share of the uterine tube closes in an introduction encompassing the ovary. The essential capacity of the uterine tubes is to transport sperm around the egg, which is discharged by the ovary, and to then permit entry of the treated egg once again to the uterus for implantation. An uterine tube contains 3 sections. The primary fragment, closest to the uterus, is known as the isthmus.
Most of the blood flow across to the left atrium through the foramen ovale. Then blood moves down into the left ventricle. It is then pumped into the ascending aorta. From the aorta, the oxygen-rich blood is sent to the brain, to the heart muscle, and to the lower body. Blood returning to the heart from the fetal body contains carbon dioxide and waste products as it enters the right atrium.
These two free ions bind together forming a carbonic acid intermediate that reacts further with carbonic anhydrase converting it back into a gas. Ventilation is controlled by respiratory centres in the brainstem. Ventilation is modified in response to inputs from sensory afferents in order to maintain homeostasis of partial pressures and pH of the blood. There are multiple types of sensory afferents related to ventilation: central and peripheral chemoreceptors, pulmonary stretch receptors, irritant receptors and proprioceptors. These sensory afferents send impulses to two anatomical regions within the central nervous system; the pontine respiratory centre and the medullary respiratory
Describe the function of the heart, cardiac cycle and circulatory system Function of the heart The heart is a muscular organ that pumps and circulates blood throughout the body via a transport system of arteries and veins and capillaries. As the blood circulates throughout the body it supplies oxygen and nutrients to the tissues as well as removing carbon dioxide and harmful waste products (Tucker, 2015). The structure of arteries Arteries have thick muscular walls and a small lumen passage. According to L. Tucker they are constructed with three layers: • A fibrous outer layer • A middle layer of muscle and elastic tissue • A lining made of squamous epithelial tissue The epithelial lining has a smooth surface to reduce friction and
The long bone is that it allows movement , particularly in the limbs eg the femur (thigh bone) tibia and fibula (lower leg bones) humerus (upper arm bone), the radius and the ulna (lower arm). Metacarpals (hand bones) metersals (foot bone) and phalanges (finger and toe bone) Functions of the skeleton The skeleton is the framework of the body; it supports the softer tissue and provides point of attachment for most skeletal muscles. The skeleton provides mechanical protection for many of the body’s internal organs, redusing risk of injury to them. Skeletal bones are attached to the muscle contract they cause bone to move, packed with over 200 bones, skeletons protect, shape support and move our bodies as well as producing red blood cells in the bone
This concept is taken from Block 4, Module 7 which is entitled as ‘Assessment of cardiovascular system’. The cardiovascular system can also be referred to as the circulatory system. It comprises of the heart and the blood vessels. The major function of the cardiovascular system is to transport nutrients and oxygen to all parts of the body and to remove waste products from the body like carbondioxide. The heart pumps the blood while the blood vessels deliver blood to all body parts.
NATOMY AND PHYSIOLOGY In this assignment the author will describe the functions and structure of the main systems of the body and their interrelationship. 1. Explain the Function of the Heart and the structure of the Arteries, Capillaries and Veins: Function of the Heart: The heart is a muscular organ in humans which pumps blood through the bold vessels of the circulatory system. Blood provides the body with oxygen and nutrients and also assists in the removal of waste. The heart is a pump that drives the whole circulatory system.
They are fertilization of egg (ovum) and sperm, cleavage, gastrulation, neurulation, organogenesis and metamorphosis (refer to Figure 1 in Appendix 1). The successful development at each stage depends on the successful complexion of the stage before. The first stage in animal development is fertilization. Fertilization is the process whereby the two sex cells (gametes) fuse together to create a new individual with genetic potential hat derived from both parents. Process of fertilization can occur in two ways; internal fertilization, process
