Cardiovascular system

cardiovascular system

Introduction

The cardiovascular system includes the heart and blood vessels. The heart pumps blood into blood vessels. Blood vessels circulate the blood throughout the body. Blood transport nutrient and oxygen to the tissues and remove carbon dioxide and waste products from the tissues.

Cardiac cycle

Cardiac CycleΒ 

The cardiac cycle is defined as the succession of ( sequence of ) coordinated events taking place in the heart during each beat. Each heartbeat consists of two major periods called systole and diastole.

Heart Sound

Heart sounds are the sound produced by the mechanical activities of the heart during each cardiac cycle “Heart sounds are produced by :

Hemorrhage

Hemorrhage is defined as the excess loss of blood due to rupture of blood vessels.Hemorrhage occurs due to various reasons. based on the cause, hemorrhage is classified into five categories:

ECG in sinus tachycardia. Normal P-QRS-T. R-R interval is shortened. Heart rate is more than 100/min

Arrhythmia

Arrhythmia refers to irregular heartbeat or disturbance in the rhythm of heart. heartbeat may be fast or slow or there may be an extra beat or a missed beat. It occurs in physiological and pathological conditions.Β 

TETRALOGY OF FALLOT

Congenital heart disease

Congenital heart disease can be the result of defects in the formation of the heart or great vessels or can arise because the anatomical changes that occur during transition between the fetus and the newborn child fail to proceed normally.

VENTRICULAR SEPTAL DEFECT (VSD)

Types of Congenital heart diseases

Congenital heart disease may be either shunts (left-to-right or right-to-left), or defect causing obstructions to flow. However, complex anomalies involving combinations of shunts and obstructions are also often present.

Congestive heart failure

Congestive heart failure or heart failure is a condition in which the heart loses the ability to pump a sufficient amount of blood to all parts of the body. Heart failure or Congestive heart failu…

Cardiac murmurΒ 

A cardiac murmur is an abnormal or unusual heart sound. It is also called abnormal heart sounds or cardiac bruit. A cardiac murmur is heard by stethoscope, along with normal heart sounds.

Respiratory system

Respiratory system

Introduction

Respiration is the process by which oxygen is taken in and carbon dioxide is given out.The first breath takes place only after birth.After the first breath, the respiratory process continues throughout the life. Permanent stoppage of respiration occurs only at death.

respiratory system

Mechanics of Respiration

Respiration occurs in two phases namely inspiration and expiration. During inspiration, thoracic cage enlarges and lungs expand so that air enters the lungs easily. During expiration, the thoracic cage and lungs decrease in size and attain the pre- inspiratory position so that air leaves the lungs easily.

Static compl

Ventilation

The word β€˜ventilation’ refers to circulation of replacement of air or gas in a space. In respiratory physiology, ventilation is the rate at which air enters or leaves the lungs.
