hormones. The different types of blood vessels are: arteries, capillaries, and veins. The vessels that carry blood towards the heart are veins and the vessels that carry blood away from the heart are arteries. Gas exchange occurs in the capillaries.
2. Describe the layers of blood vessels. Describe the differences between arteries and veins.
The layers of blood vessels are: a hollow interior (lumen), contains an outer…
c) Pulmo-cutanous arch- it divides into
Pulmonary artery – it receives deoxygenated blood from different parts of the body and open into lungs.
Cutanous artery- it supplies oxygenated blood to skin.
Venous System of frog
Blood vessels, which carry the deoxygenated blood from different parts of the body to the heart, are called veins. They constitute a system called venous system.
Venous system of frog can be studied under too heading
A) Systemic Venous System
This system includes the three…
M1 outline the adaptations to cardiovascular, respiratory, musculoskeletal and energy systems, brought about by regular exercise
The cardiovascular system consists of the blood vessels and the heart. They function is to circulate the blood around the body to all the muscles. The red blood cells carry oxygen to all the muscles through the vein (carries blood to the heart). The veins have thin walls and contain blood under the low pressure. The arteries (carries blood away…
the procedure because it will decrease the patient’s anxiety. Cardiac catheterization involves a catheter called a fluoroscope that is inserted into either the right or left side of the heart to assess any septal defects, abnormalities, or any dysfunctions that are occurring within the heart. Depending on which side of the heart needs to be viewed will depend on if the catheter will be inserted into the artery or vein. In the left side, the catheter will be inserted into either the brachial or…
peritoneal cavity. The arrow could have reached the posterior mediastinum.
b) “Identify and describe the organs and any other membranes that may have been affected by the first arrow.”
The first arrow might have reached the pericardium and pericardial cavities on the posterior mediastinum and the posterior thoracic wall causing damage to the membranes in the vicinity. It is likely that it affected organs such as heart, the inferior vena cava, the aorta and the pulmonary artery. This…
procedures today (Walker, 2007). A good surgical team will increase the success rate
of the total hip replacement. However, proper nursing interventions during pre-operative and
post-operative phase of the surgery is very important for the patient. Nurses spend more time
with patients compared to the other health care personnel. Therefore, a good nursing care will
better prepare the patient before the surgery, accelerates healing post-surgery, and prevents
further complications (Walker,…
1. Anatomy of the trachea and bronchi.
The trachea (Fig.1) is a cartilaginous and membranous tube, extending from the lower part of the larynx, on a level with the sixth cervical vertebra, to the upper border of the fifth thoracic vertebra, where it divides into two main bronchi, one for each lung. The trachea is nearly but not quite cylindrical, being flattened posteriorly; it measures about 11 cm. in length; its diameter, from side to side, is from 2 to 2.5 cm., being always greater in…
Blood is the biological fluid in our body that transports nutrients and oxygen to the cells, and also exports the metabolic waste product away from the cells. To ensure the supply of oxygen needed by our organs and tissues, there are four important steps:
1. The oxygen must be transferred from our lungs into the blood plasma
2. The oxygen is stored on the hemoglobin in the red cells
3. The oxygen is transported to our body cells via circulation.
4. The oxygen is released…
Hyaloid canal: The hyaloid canal is a small, transparent tunnel that traces its path through the vitreous body of the eye, spanning the optic nerve disc to the lens. In an adult person, the hyaloid canal carries lymph to help change the volume of the lens. When the lens expands, the hyaloid canal compresses, so that the eye’s internal pressure and volume remain constant (Merriam-Webster).
Optic nerve: A part of the central nervous system, the optic nerve connects the eye to the brain, carrying…
Coronary arteries are one of the most important parts of the body because of many different factors. Heart muscle needs blood rich in oxygen to function and pump more blood throughout the circulatory system. If the blood does not carry enough oxygen, the veins will carry it away. Blood can only be delivered when the heart is relaxed; because once they contract they become narrow. These arteries are structured differently as opposed to many of the other arteries in the human body. The coronary…
