Slide 1-

Introduction to the Human Cardiovascular System Dr. Rakesh Kumar Verma Assistant Professor Department of Anatomy KGMU UP Lucknow
Slide 2-

INTRODUCTION The cardiovascular system is transport system of body It comprises blood, heart and blood vessels. The system supplies nutrients to and remove waste products from various tissue of body. The conveying media is liquid in form of blood which flows in close tubular system. Figure 1-2(f)
Slide 3-

FUNCTION OF CARDIOVASCULAR SYSTEM Transport nutrients, hormones Remove waste products Gaseous exchange Immunity Blood vessels transport blood Carries oxygen and carbon dioxide Also carries nutrients and wastes Heart pumps blood through blood vessels
Slide 4-

COMPONENTS OF CARDIOVASCULAR SYSTEM BLOOD HEART BLOOD VESSELS
Slide 5-

BLOOD The Blood: Blood cells & Plasma Blood cells 1- Erythrocytes - Red Blood Cells 2- Leucocytes 3- Thrombocytes Plasma is fluid portion
Slide 6-

HEART Heart is a four chambered, hollow muscular organ approximately the size of your fist Location: Superior surface of diaphragm Left of the midline Anterior to the vertebral column, posterior to the sternum Chapter 18, Cardiovascular System 6

HEART Chapter 18, Cardiovascular System 7 Figure 18.1

Slide 9-

FUNCTIONS OF THE HEART Generating blood pressure Routing blood Heart separates pulmonary and systemic circulations Ensuring one-way blood flow Heart valves ensure one-way flow Regulating blood supply Changes in contraction rate and force match blood delivery to changing metabolic needs
Slide 10-

BLOOD VESSELS Blood Vessels -A closed network of tubes These includes: Arteries Capillaries Veins
Slide 11-

BLOOD VESSELS -Arteries(Distributing channel) Thick walled tubes Elastic Fibers Circular Smooth Muscle Capillaries (microscopic vessels) One cell thick Serves the Respiratory System Veins (draining channel)
Slide 12-

BLOOD VESSELS General structure 1.Tunica intima 2.Tunica media 3.Tunica adventitia
Slide 13-

CLASSIFICATION OF BLOOD VESSELS Conducting Vessels Distributing Vessels Resistance Vessels Exchange Vessels Capacitance / Reservoir Vessels
Slide 14-

ARTERIES Blood vessels that carry blood away from the heart are called arteries. They are the thickest blood vessels and they carry blood high in oxygen known as oxygenated blood (oxygen rich blood).
Slide 15-

ARTERIES Accompanied by vein and nerves Lumen is small No valves Repeated branching
Slide 16-

CLASSIFICATION OF ARTEIES Elastic- e.g. (Aorta & its Major branches) Muscular -e.g.(Renal, Testicular, Radial, Tibial etc.) Arterioles (<0.1 mm)- Terminal arterioles Meta-arterioles Thoroughfare channel/ preferred
Slide 17-

CAPILLARIES (5-8 micron) The smallest blood vessels are capillaries and they connect the arteries and veins. This is where the exchange of nutrients and gases occurs.
Slide 18-

BODY CONTAINS TWO KINDS OF CAPILLARIES CONTINUOUS-SKIN, LUNG, SMMOTH MUSCLE, CONNECTIVE TISSUES FENESTRATED- PANCREAS,ENDOCRINE GLANDS, SMALL INTESTINE,CHOROID PLEXUS,CILLIARY PROCESS etc.
Slide 19-

SINUSOIDS SINUSOIDS- Large irregular vascular space (30-40 micron) eg.Liver, Spleen, Bone marrow, suprarenal, Parathyroid etc.
Slide 20-

VEINS Blood vessels that carry blood back to the heart are called veins. They have one-way valves which prevent blood from flowing backwards. They carry blood that is high in carbon dioxide known as deoxygenated blood (oxygen poor blood).
Slide 21-

VEINS Thin Walled Large irregular lumen Have valves Dead space around Types: Large Medium Small
Slide 22-

VEINS Veins without valves: SVC & IVC Hepatic, Renal Uterine, Ovarian not Testicular Facial Pulmonary Umbilical Emissary Portal Veins <2mm
Slide 23-

VEINS Veins without Muscular tissue: Dural venous sinuses Pial Veins Retinal Veins of erectile tissue of sex organs Veins of spongy bones
Slide 24-

VEINS Factors responsible for venous return: Muscle contraction Negative intrathoracic pressure Pulsation of arteries Gravity Valves
Slide 25-

ANASTOMOSIS Communication between vessels ARTERIAL: Actual( end to end & convergent)-Palmar, plantar, Circle of Willis, Labial Intestinal arcade, etc. Potential-Coronary, around joints etc.
Slide 26-

ANASTOMOSIS ARTERIOVENOUS ANASTOMOSIS: Skin of nose Lips External Ear Mucus membrane of GI & nose Erectile tissue of sex organ Thyroid Tongue
Slide 27-

END ARTERIES END ARTERIES: Central artery of retina Arteries of spleen, liver, kidneys, metaphyses of long bones Central branches of cerebral cortex
Slide 28-

CIRCULATION Coronary circulation – the circulation of blood within the heart. Pulmonary circulation – the flow of blood between the heart and lungs. Systemic circulation – the flow of blood between the heart and the cells of the body. Fetal Circulation
Slide 29-

SYSTEMIC AND PULMONARY CIRCULATION Pulmonary circulation The flow of blood between the heart and lungs. Systemic circulation The flow of blood between the heart and the cells of the body. Chapter 18, Cardiovascular System 29 Figure 18.5
Slide 30-

Chapter 18, Cardiovascular System 30 CORONARY CIRCULATION: ARTERIAL SUPPLY Figure 18.7a
Slide 31-

PORTAL CIRCULATION Portal circulation - the flow of blood between tow set of capillaries before draining in systemic veins.

APPLIED Diseases and Disorders BLOOD PRESSURE HAEMORRHAGE/STROKE ARTERIOSCLEROSIS ANEURYSM CORONARY ARTERY DISEASE (CAD) HEART ATTACK CONGESTIVE HEART FAILURE (CHF) ANEMIA, HEMOPHILIA, AND LEUKEMIA
Slide 35-

APPLIED Problems with the cardiovascular system are common, but they don’t just affect older people. Many heart problems affect children and teenagers.
