Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium.
Vascular smooth muscle cells control the size of the vein lumens, and thereby help to regulate blood pressure. [31] The inner tunica intima is a lining of endothelium comprising a single layer of extremely flattened epithelial cells, supported by delicate connective tissue. [8] This subendothelium is a thin but variable connective tissue. [4]
The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [ 1 ][ 2 ] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and from Latin vascula ...
The circulatory system uses the channel of blood vessels to deliver blood to all parts of the body. This is a result of the left and right side of the heart working together to allow blood to flow continuously to the lungs and other parts of the body. Oxygen-poor blood enters the right side of the heart through two large veins.
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis – Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue – The primary components of vascular tissue are the xylem and phloem.
Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, [ 1 ] using the methods of mechanics. [ 2 ] Biomechanics is a branch of biophysics. Today computational mechanics goes far beyond pure mechanics, and involves ...
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
Inside this layer is the tunica media, which is made up of smooth muscle cells, elastic tissue (also called connective tissue proper) and collagen fibres. [3] The innermost layer, which is in direct contact with the flow of blood, is the tunica intima. The elastic tissue allows the artery to bend and fit through places in the body.
