Internal jugular vein

internal jugular veins as well. As the external jugular veins descend through the lateral neck, they pass obliquely over the sternocleidomastoid muscles and then empty into the subclavian veins. The brachiocephalic vein a vein that returns oxygen-depleted blood from the upper limbs, neck, and head to the heart. There is a brachiocephalic vein on the left side of the neck and one on the right. The two brachiocephalic veins merge together with the azygos vein, which carries deoxygenated blood from the rib cage, to form the superior vena cava. The blood that flows into the heart from the superior vena cava is controlled by the contractions of the heart. The basilic vein is a large blood vessel within the arm. Between the shoulder and the elbow, this vein courses underneath muscle tissue.…

connected by an isthmus in the middle. The thyroid gland is mainly supplied by the superior thyroid artery, the first branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk of the subclavian artery; and occasionally by the thyroidea ima artery, an infrequent branch of the arch of the aorta. The venous drainage of the thyroid gland is into the internal jugular vein through the superior and the middle thyroid vein; and by the inferior thyroid…

Jugular Veins The most accessible veins for examination are the internal and external jugular veins in the neck. Both veins drain bilaterally from the head and neck into the superior vena cava. The external jugular vein lies superficially and is just above the clavicle. The internal jugular vein lies deeper, along the carotid artery. It is best to examine the right internal jugular vein because it follows a more direct anatomical path to the right atrium of the heart. The column of blood inside…

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…

household and trying to survive off marginal lands from natural disease such as flood or drought. “The remaining 20 percent live in shanty towns on the periphery of the biggest cities in developing countries. The numbers of poor and hungry city dwellers are rising rapidly along with the world 's total urban population (wfp.org 2015).” In many traditions cultural and social structure, women are the world’s main food producer, often women are much more affected by hunger and poverty than men. For…

Introduction The cardiovascular system is a fundamental system for survival, providing the body nutrients and removing waste via a network of arteries, arterioles, capillaries venous and veins. (Sherwood). Understanding this fundamental system is critical to help further understand even more complicated medical conditions such as Postural orthostatic tachycardia syndrome (POTS), inappropriate HR increase when standing (Freeman et al., 2011). In addition, the cardiovascular system also has…

1. Auscultation method is more accurate by using the stethoscope to listen for systolic blood pressure compared to palpation of systolic blood pressure at wrist. It is easier to listen for the ‘tap’ during the systolic pressure rather than palpating for it, as the systolic pressure may not be palpated if it is a weak pulse. 2. Systolic pressure: • Pressure in the arteries when the blood is being pumped out of the heart into the arteries • The maximum blood pressure, when the ventricles are in…

flow, rigid vs. distensible tubes, Newtonian fluid vs. blood. Antiplatelets are a group of medicines that stop blood cells (platelets) from sticking together and forming a blood clot. Whenever there is an injury in your body, platelets are sent to the site of the injury, where they form a blood clot. This is a very important mechanism in the body to stop the bleeding. Prevents formation of blood clots, for example in the carotid arteries. Anticoagulantants are chemical substances that prevent…

Blood donation is a safe process as sterile needles are used only once on a patient and is then discarded afterwards. Therefore people should not worry about getting AIDS. It is also a simple three-step process consisting of screening(where the donor is asked to complete and show his or her ID card, then the donor is asked some health story questions then temperature, blood pressure, pulse and hemoglobin are checked to ensure donor’s blood is safe to use.), donating (where the donor is asked to…

Furthermore, the more we exercise changes would occur in our cardiovascular system. When performing exercise, your muscles would need sufficient amount of oxygen and nutrients so that you can perform well. Also, the carbon dioxide produced should be released from the body. It is the main role of the heart to pump harder and faster when exercising so that oxygen is taken in and carbon dioxide is released as a by-product. There are many acute changes that occur in this system before, during and…
