Connective tissue often consists of relatively few cells embedded in an extracellular matrix.(This describes many connective tissues, such as loose connective tissue)

One of the four main forms of animal tissue, along with epithelial, muscular, and nerve tissue, is connective tissue, often known as fibrous tissue. It arises from mesenchyme, which is derived from the intermediate embryonic germ layer known as mesoderm. All of the body's tissues, including the neurological system, are connected by connective tissue. There are three meninges, which are connective tissue-based membranes that cover the brain and spinal cord. Elastic and collagen fibers, ground material, and cells make up the majority of connective tissue types. Specifically fluid connective tissues without fibers include blood and lymph.

Catecholaminergic polymorphic ventricular tachycardia is a genetic condition characterized by exercise-induced ventricular arrhythmias and/or cardiac syncope, as well as an elevated risk of sudden cardiac death.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a hereditary condition that predisposes people to potentially fatal irregular cardiac rhythms or arrhythmias. CPVT arrhythmias generally develop during exercise or during periods of emotional stress and take the form of bidirectional ventricular tachycardia or ventricular fibrillation. Those affected may be asymptomatic, but they may also have blackouts or even die suddenly. Genetic mutations affecting proteins that regulate calcium concentrations within heart muscle cells cause CPVT. The most widely recognized gene is RYR2, which encodes a protein that is part of an ion channel known as the ryanodine receptor; this channel releases calcium from the sarcoplasmic reticulum, a cell's internal calcium storage, with each heartbeat. An ECG obtained during an exercise tolerance test is commonly used to diagnose CPVT, however a genetic test may also be used. The condition is treated with medicines such as beta-adrenoceptor blockers or flecainide, as well as surgical techniques such as sympathetic denervation and defibrillator implantation.

The surface area-to-volume ratio of a cell decreases as its size increases.

The surface area of a cell expands as the square of its radius, while its volume increases as that of the cube of its radius plant. Cells must continually interact with their surroundings in order to live. Gases and food molecules that the cell requires are dissolved in water and must be absorbed, as are waste products of cellular metabolism. All materials enter and exit the cell via the plasma membrane. The interior volume of a cell rises as the cell membrane expands. Because volume rises faster than membrane surface area, the relative quantity of surface area accessible to transmit materials to the a unit volume of a cell continuously declines.

As a result, if the cell develops beyond a certain point, not enough material would be capable of crossing the membrane quickly enough to meet the increased metabolism that occurs as the cellular volume rises. As a result, the cell must either split into smaller cells with favorable surface area/volume ratios or stop functioning.

Change in leaf colors is called photoperiodism. Autumn leaves change color because the amounts of pigments in the leaves change as they prepare to fall from the trees.

During the growing season, all leaves gradually lose chlorophyll, and this loss accelerates before leaf fall. Under ideal conditions, this process of chlorophyll loss is very orderly, allowing plants to resorb much of the nitrogen in the pigment molecule structure. Carotenoid pigments are also lost from the plastids as they age, but some of them are retained after the chlorophyll is removed, resulting in yellow autumn leaves. In unusual cases, sometimes in winterberry holly, a fair amount of chlorophyll is left in the leaves when they fall. The mixture of chlorophyll and carotenoids results in leaves that are pale green or yellow-green in color.

Leaves play an important role in excretion in plants. They are responsible for removing waste products, such as carbon dioxide and water, that are produced during photosynthesis and cellular respiration.

One of the main ways that leaves excrete waste products is through transpiration, which is the process of releasing water vapor from the leaves through small openings called stomata. This process not only helps to remove excess water from the plant, but it also helps to release waste gases such as carbon dioxide and oxygen that are produced during photosynthesis.

Leaves also excrete waste products through guttation, which is the release of water droplets from the leaves. This process helps to remove excess water that is not needed by the plant.

Additionally, leaves also excrete waste products in the form of excess minerals, which are not needed by the plant and are removed via root exudation.

In summary, leaves play a crucial role in excretion in plants by releasing waste products such as carbon dioxide, water, and excess minerals via transpiration, guttation, and root exudation.

Antidiuretic hormone   also aids the stress response by promoting water retention and acting as a vasoconstrictor .

Additionally, vasoconstriction and elevated arterial blood pressure are both effects of antidiuretic hormone. Low serum sodium and low serum osmolality together with a rise in serum ADH suggests that the hormone is secreted in response to a nonosmotic stimulation. Vasopressin, also known as antidiuretic hormone, is released into the bloodstream by the pituitary gland when the body is dehydrated. Vasopressin prompts the kidneys to conserve water and produce less urine. Blood pressure rises as a result of antidiuretic hormone's extrarenal role as an arterial vasoconstrictor. In response to a water load, plasma osmolality drops and ADH release is suppressed.

Water retention and bloating can result from high oestrogen and low progesterone levels. Progesterone is a naturally occurring diuretic, whereas oestrogen frequently operates as a hormone that retains fluid.
